RADIATOR.

Application filed July 16,

To all whom it may concern:

Be it known that 1, DAVID J OHN ARCHER, a subject of the King of Great Britain, residing in the city of Toronto, county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

My invention relates to improvements in radiators, and the object of my invention is to provide a demountable leak-proof rad1ator of that character in which currents of air circulate interiorly and exteriorly of the conduits conveying the heating-medium so that the radiator will not only be cheaper to manufacture than those of like character, but it will possess the decided advantage of permitting repairs to be easily made on site, and in the following specification I shall disclose my invention, and what I claim as new will be set forth in the claim forming part of this specification.

F ig. 1 is, in part, a vertical central longitudinal section through one of the radiator sections, and a side elevation of one of the radiator sections. Fig. 2 is a plan view of two radiator sections coupled together, and Fig. 3 is a horizontal cross section on the line 3-3, Fig. 1.

In the drawings, like characters of reference refer to the same parts.

It is already known in the prior art to pass currents of air interiorly and exteriorly of conduits conveying the heating-medium, but the air conduits, as well as the heatingmedium conveying-conduits are expanded or screwed into the headers, and consequently it is impossible to make repairs on site. Furthermore the headers, both top and bot tom are not usually sectional, thus further increasing the difficulties in making repairs.

Now in putting my invention into practice, the headers are made in sections, and adjacent sections are coupled together by nipples or other suitable coupling means swedged in place, in place, and the heatingmedium conveying-conduits, as well as the air conduits are also swedged in the header sections after the particular manner hereinafter noted.

The top and bottom headers are identical, in construction, and the same comprise a plurality of header sections A which are each laterally provided with coupling members B preferably integrally formed therewith, each formed with a cylindrical bore,

by counter-boring, each of which terminates at its inner end at a grooved flange D. The construction described is for the purpose of providing extended packing surfaces for coupling means andswedged in said coupling members are the nipples or other removable coupling means C whereby adjacent header sections are removably coupled together. The inner ends of the nipples C are hushed around the flanges D. The coupling members B each open into a central chamber E. In its vertical construction, each header section embraces two longitudinally disposed cylindrical sections 5 and 6, the

latter of greater horizontal diameter than the former, and separated almost entirely by an annular chamber G. These cylindrical sections are initially cored out at the time each header section is cast, and they are located in pairs laterally of the coupling members B. Each annular chamber G has communication with its associated central chamber E through a port F.

Each cylindrical section 5 and 6 is counterbored to provide extended packing surfaces as shown at H and 2. At the same time each of the said cylindrical sections is counter-bored, each is provided respectively with a grooved flange 1 and 3. The outer ends of the conduits H and 4 are swedged in their respective cylindrical sections?) and 6, and the extreme ends of these conduits extend into the grooves of the said flanges.

I are the air openings through the cylindrical sections 5, and communicate with the conduits H through which air flows.

The heating medium flows through the conduits i, and therefore tl'iediameter of each flange 3 must be greater than the external diameter of its associated conduit H to permit flow of the heating medium into and out of each conduit 4 through the medium of the annular chambers G.

From what has been stated it is evident that since the conduits H and 4 are swedged in place as are also the coupling means or nipples C, in case of repairs these various elements can be readily uncoupled on site.

Of course suitable means will be employed to close the ends of the end header sections, and to support the radiator, but as these are not germane to the invention they are not illustrated.

Obviously a radiator embodying the principle of this invention may comprise two as scciated conduits H and a supported at each end by a header section adapted to permit air to flow therethrough and to permit the heating-medium to properly circulate.

It must be understood that the disclosure herein is not to be construed as confining me to the details of construction herein disclosed.

What I claim is:

A radiator comprising a top and bottom header each having a chamber provided with an inlet and an outlet, and each integrally formed, and each embracing two longitudinall -disposed cylindrical sections, the inner of which is of greater horizontal diameter thanthe outer one, and into each of which opens a passage-way which is part of said chamber, theouter end of each cylindrical section-having an opening thereinto, and

each of the said sections being counter-bored to provide extended packing surfaces; a grooved flange located at the opening into each of the smaller cylindrical sections; a

tubular air conduit swedgcd at its ends in' said smaller cylindrical sections, and having its extreme ends located in the associated groovedflanges; a grooved flange located at the inner end of the counter-bore of each larger cylindrical section and of greater diameter than said air conduit which passes therethrough, and communicating with its associated passageway, and a heatingmedium-conveying conduit swedged in each counter-bored larger cylindrical section and having its ends packed in the associated grooved flanges thereof.
